CHARLES W. HUNT, OF NEW YORK, N. Y; KATHARINE H. HUNT, CHARLES WALLACE HUNT, AND GEORG-E' S. HUMPHREY EXECUTORS OF SAID CHARLES W. HUNT,-

.To all whom t may concern.' y

Be it known that I, CHARLES VALLACF. HUNT, a` citizen of the United States, resulving in Stapleton, inthe boroughot Richupon the truck for .the purpose of obtaining the maximum tractive effort, while the gage of t-he track 1s narrow, the radius of curves is short and. the roadbed sometimes uneven,-

so that each truck must have considerable flexibility.

The object of the invention is to produce an improved motor truck which will meet the requirements of use imposed by the condit-ions referred to.

The invention will be more fully explained hereinafter with reference to the accompanying drawing in which an embodiment thereo't'iis illustrated and in which" 4truck vand a carrying truck.

and the carrying Wheels e Figure l is a view partly in elevation and partly in section showing a portion of a railway car with the improved motor truck in place. Fig. 2 is a top view of the motor truck shown in Fig. l. Fig. 3 is a view in elevation, partly iifsection, on a smaller scale `than Figs. 1 and 2, indicating the whole of the car body and both a motor In the embodiment of the invention represented in the drawing the car body a shown as supported upon the bolster b of the truck., The bolster is secured to the side frames c and the latter may be provided with journal boxes, notv shown, for the axles d, d', provided with the driving wheels e, e, e respectively. The `motor 7", which may be of any suitable character, is mounted upon one end of a frame gl which hastwojournal boxes g to DECEASED.

As shown 1n Figs. l and 2 a worm h on the armature shaft L of the motor engages a worm gear ILL Vtixed outhe driving axle'd. It will now be seen that the. motor frame has a three point bcarmg, two pomts on the driving axle and one point (in the con-` struction shown) on the carrying axle, so that the truck has the necessary flexibility while the motor is maintained always in definite relation to the driving axle.` Furtherniore with the extension of the motor frame in one direction, beyond thel driving axle d, away from the carrying axle 0l or point of support of thc other end of the frame y, to receive and support the motor, nearly all of the weight of the truck, 'motorl frame, in'otor and a corresponding portion ot' the car body is supported directly uponthe driving wheels e so that an increased tractive effort is produced, the 'carrying wheels c sustaining only so much of the weight as is necessary to keep them .upon

the rails.

It will be understood that the details of' construction and arrangement may be varied to suit different conditions of use and that the invention is not restricted to the particular construction shown and l'described herein.

It will also be understood that although the invention is shown in .the drawings as applied Ato an eight wheel car,vit is equally applicable to a .four wheel'car, the word truck being used with* a broad `signification. i t' Iclaim as my invention: y

A motor truck comprising a driving axle and'wheels, a carrying axle and Wheels, a-
